Question
A researcher is interested whether a new drug is effective in changing patients' cholesterol levels. She divided 39 patients into 5 groups according to the dosage the patient received. The cholesterol levels of all patients are measured and used as the data for the Analysis of Variance (ANOVA). If she reported the test statistic F = 4.1 What is the degree of freedom for the numerator of the F statistic? What is the degree of freedom for the denominator of the F statistic? What is the P-value of the F-test? (Round to 3 decimals) Given the significance level of 0.1, what can she conclude from the test? The patients in differnt groups have simliar average cholesterial levels. The drug made no difference. At least one group of patients have an average cholesterol level that is different from the other groups. The drug may have an effect.
